You've got halfway through it! All you have to now is set the two equations equal to each other and solve for x.
2500+0.03x=1500+0.035x
1000+0.03x=0.035x
1000=0.005x
200000=x
$200,000
Good luck!

Answer is A
Answer:
A) A = X^2 + 11X + 24
B) X = 18 ft
C) 414 ft^2
D) 132 ft^2
Step-by-step explanation:
A) Width W of yard and path = X + 3
Lenght L of path = X + 5 + 3 = X + 8 ft, therefore,
Area of yard and path = L x W = (X +3) x (X +8)
A = X^2 + 11X + 24
B) if area of the yard and path is 546 ft^2,
546 = X^2 + 11X + 24
X^2 +115X - 522 = 0 (quadratic equation)
Solving the quadratic equation gives
X = 18 and X = -29
Our answer can only be positive so we choose X = 18 ft
C) lenght of yard = 5 + 18 = 23 ft
Width = 18 ft
Therefore area = L x W = 23 x 18 = 414 ft^2
D) area of path = area of path and yard minus area of yard
= 546 - 414 = 132 ft^2
Answer:
r=-3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4r−3=3(3r+4)
4r+−3=(3)(3r)+(3)(4)(Distribute)
4r+−3=9r+12
4r−3=9r+12
Step 2: Subtract 9r from both sides.
4r−3−9r=9r+12−9r
−5r−3=12
Step 3: Add 3 to both sides.
−5r−3+3=12+3
−5r=15
Step 4: Divide both sides by -5.
−5r
−5
=
15

Mark me brainliest if this helped :D
The first one is 3 . To find each of the others, multiply the previous one by 3 .
